Hi Thomas, On mer., ao?t 30 2017, Thomas Petazzoni [off-list ref] wrote:
The Armada AP806 has 20 pins, and therefore 20 GPIOs (from 0 to 19
included) and not 19 pins. Therefore, we fix the Device Tree
description for the GPIO controller.
Before this patch:
$ cat /sys/kernel/debug/pinctrl/f06f4000.system-controller:pinctrl/gpio-ranges
GPIO ranges handled:
0: mvebu-gpio GPIOS [0 - 19] PINS [0 - 19]
0: f06f4000.system-controller:gpio GPIOS [0 - 18] PINS [0 - 18]
After this patch:
$ cat /sys/kernel/debug/pinctrl/f06f4000.system-controller:pinctrl/gpio-ranges
GPIO ranges handled:
0: mvebu-gpio GPIOS [0 - 19] PINS [0 - 19]
0: f06f4000.system-controller:gpio GPIOS [0 - 19] PINS [0 - 19]
Fixes: 63dac0f4924b9 ("arm64: dts: marvell: add gpio support for Armada 7K/8K")
